Albert Marth discovered NGC 6632 = m 380 on 24 Jun 1864 and noted "F, S, R, gbM." His position is fairly accurate. E.E. Barnard found it while sweeping on 30 Jan 1889 with the 12-inch refractor at Lick Observatory and noted "Faintish, R, vgbM, 2 small stars involved preceding, 1' diameter." He later added in his logbook the correct identification.

400/500mm - 17.5" (7/1/89): fairly faint, fairly small, elongated NW-SE, large brighter core. A pair of mag 12 and 13 stars lie 1.3' W and 1.0' NW of center, respectively. A group of brighter stars are about 7' S including mag 6.3 HR 6904 8.5' S.
